From the shoe and the insertion centerof the die-block, which is withou't 'the usual nail'openings, rises a standard e r-sup port 20,1'ecessed at 22' to receive tool-carriers and nail-holders furnished by these tubes, fivefappear, one attaching nails to I ditional nail'at the center of the heel-breast, the inserting mechanism for which will be described later;

tubes 24 Of 5 for each of the be driven, except'for an ad Each of 'the tubes and its mounting is identical, save as to position, and I but one (if thesewill be consideredin detail. Projecting from the upper portion of the i standard 20 at each tube-position are brackets 26, in which are alined horizontal semi-cylindrical depressions 28 to receivetrunnions 30 extending oppositely from the top of the tube. To hold the trunnions in the bracket-depressions, I provide a cover-plate 32 havingregistering depressions and secured'to the topof the standard. WVithi the tube is the operating tool, in thisinstance a driver 34 having the customary cylindrical form. At its lower end, the driver fits within a, reduced bore 36 in the tube, while about its upper end is a bushing 38 arranged to slide in the tube-opening. This bushing surrounds the driverholde r s0, and has pivoted to it at 42 a link 44 passing through a vertical slot 46 in the carrier. The link is articulated at -18 to lugs depending from a plate 50 received in ways 52 in the top girt. 'The tube is free to swing between an inner position, in which it is sun stantially vertical, outwardly, the lower portion traveling through a slot 54: in the block 12 until it is arrested by contact with a plate 56 secured upon the top of the block by a slotand-screw connection 58.- The plate, variable inposition by virtueof this connection per mits the limit of outward movement of the carrier to be changed. The tube has mounted upon it a friction device, in the form of a plug 60, movable through a horizontal bore in a boss 62 and pressed inwardly into contact with the driver by a spring 6 1- abutting at its outer eXtremity against ascrew 66 threaded .,into the boss-opening. Movement of the screw permits the tension of the spring, and thus the pressure exerted by the plug upon the driver to be varied. Observing that the pivotal connection 42 between the driver-carrier and link is below the pivotal support of the carrier by the trunnions 30, and thatlthe link 44 1S inclined downwardly and inwardly Irom the pivot i8 to the pivot 42, it will be seen that,

assuming the carrier to be at. the outer limit of its movement, downward travelof the actuating member or top girt 16 will first exert, through. the link 14, a pressure upon the carrier, swinging it inwardly about the trunnions 30, the resistance to movement about the carrier-pivot being less than that exerted by the friction device acting through the plug 60 upon the driver. This movement continues until it is arrested by contact of a gage-sur-- face upon the carrier with the heel-portion L which is to be attached. The gage is shown asconsisting of a projection 68 depending from the outer side of the carrier at its lower exertmityand having-an inner vertical face 69arranged to contact with the liftL as it is supportedupon the shoe and base located by the pins 19. Theea-rrier thus being positively held againstmovement, the plug 60 slips over the driver 34, so that continued downward travel of the top gut and link carries the driver through thetube for the insertion of thefastening. To adapt the apparatus to act at different distances fromthe periphery of the work, able upon the carri eutubes;

instance, they are springs 71 securedto the tubes at their upper extremities, The tendency of these In the present springs is to urge the projections outward.

' scissors the projections .68 may be adjust siown as mounted on Lesaesr riers through flexible tubes 72 from a distributor 7-1- carriedupon the frame l0atthe rear of the machine. This dlstributorlmay be of 'anv suitable t 3e as that illustrated in Patout No. 1,005,308, Pope, Oct. 10, 1911. To re tain the nails to receive the action of the drivers, each tube has associated, with the delivery-opening, below the junction ofthe pas sage with the, bore 36, a nozzlei'ii, formed in halvesdivided vertically. These sections of each nozzle are located in oppositevertical recesses 7 8 at the sides of the carrier-tube, and have at their upper and lower portions an'gu lar ends 80, the upper of which lie in trans verse recesses 82, while thelower moveacross the end of the tube. The engagement between the end-portions and the tube is such as to permit oscillation of the sections about the upper positions as pivots, While the lower portions furnish guides in this movement; At the bottom of each nozzle-section is arounded delivery-end 84-, through which is a contracted passage 88, axially alined with the bore 36. The nozzle-sections are normally held together, with thedeliVery-opening of the passage so contracted that a nail supported with in. it will be retained, by a spring 88 of the type, with its convolutions encircling a pin 90 carried in lugs 92 upon the gage member 08. Tlhe arms 94 of this scissorszle, holding them yieldably together.

.In using the apparatus for the attachment of a rubber-lifufthe shoe S, with the heelbase H previously secured thereto and both provided with locating openings, may be placed uponlhe jack 18 in the openings, and the lift L1 located upon the base by the engagement of the pins'with its depressions. Upon theupwardmovement of the top girt from the.'preceding nailing with the pins 19 with-I llll operation, the distributor-74L wastripped in the usualmanner, delivering a charge of nails to the conduits 72. Falling-through the conduits and passages 70, thesenails' enter the bores 36, and are held with theirpoints downward by the sections of'thef ozzles 76 closed by the springs 88. Theicarri'ertubes 24 are atthis time against the stopplates 56 as a result of the upward movement f the top girt, the links 44 having first-swung out the carriers '24 abouttheir trunnions 30,

after the pressure upon the work had been released, by the descent of the jack, until they were stoppedby the plates 56, the fri'cslipping to tion at the plugs 60, thereafter allow the full elevation of the drivers. Thus, for each operation, the carrier-tubes are found separated to their full extent, adapting them tojengage' the periphery of what'- ever size lift is to be attached. When the formed carrier.

" having claim machine startedforthe' current operation,- the descent otthe top portions '68 oi'the carriers into contact with the edge of the lift, the' friction' at 60 resisting movement of the drivers. I By this engagement with the work, each of the'noz- Zles 76 is located at the-correct distance from the periphery of the heel forfthe insertion it carries. The space be-' of "the nail which tween the delive y-opening 86 of each noz- Zle and its corres is arranged 'to determine this. tion of the nozzles with reference to I been thus gage'd, the thecontact-surfaces stops the movement of the carriers, and the slipping of the triotifonal connections allows theidescent" of the drivers under the influence of the links, they striking the heads of the nails supported n the nozzles and driving them "through these,

the sections opening to permit their passage into the lit-t and'base to attach the former.

The nail which is inserted at the center er thebreastbi' the heel, on account of'its relation to the locating driven in the same position 'for a'll sizes otheels. Consequently, the driver 96 for this nail may be connected directly to the plate 50 at "98' and operates within a passage 100 the support 20'. The passage 70, through iv distributor to receive-the action of this driver, and the nOZZle'ZG, which terminates it, may be thesame as these elements already described in connecti n, with the oscillatory drivers.
